@uiten gisten gstmt @frn TOY BUILDlNGr-BLOGKS` SPECIFICATION.

To am. wHoM 1r MAY eoNoERNr Be it known that I, GEORGE H. CHINNOCK, ofthe city, county, and State of New York, have invented a new and usefulimprovement inA Toy or Building-Blocks and I do herby declare that thefollowing is a full,

clear, speciication, in which- Figure 1 is .a plan view of rtwo of myblocks,l standing uponend, and so placed together ,as to form a cube,showing the manner in which a letter, a part of which isV situated uponthe end of each block, is completely represented by their being placedtogether.

Figure 2 is a perspective view of one of my blocks. Figure 3 is a plansimilar to fig. 1. Figure 4; is an elevation showing the manner in whichmy blocks may be einployedin building a toy-house. Similar letters ofreference indicate corresponding parts in all the figures. v

and exact description of the saine, reference being had to the annexeddrawings, making a part of this v The object of this invention is tofurnish an instructive amusement for children; and it consists in anovel i construction of toy or building-blocks, in the-form of cubesdivid'ed diagonally in planes perpendicular to two of their sides, theblocks having letters or numerals marked upon them in such a way as toadmit, in 'connection the-peculiar shape of the block, of amuchgreaternumber of combinations, and to eallrforth'much more ingenuity intheii` employment, than has been thecase with the toy-blocks heretoforedevised. 'To enable others to understand the' nature and construction ofmy invention, I will proceed to describeit, with reference to thedrawings. y

The blocks are formed simply by dividing cubes diagonallyv in planesperpendicular to two of, their sides, and consequently have their endsthree-sided, or 'triangular inform, as shown at a, while Atwo of thesides, b b, are square, and the remaining one', formed by cuttingthrough -or dividing the cube, as aforesaid, is a -rectangular,quadrilateral in shape. This five-sided shapeallows the blocks tobearrangedwith reference to each other in various ways, so as to form atoybuildingI which couldz'ynot Vbe, constructed with the ordinarycubical or sii-sided blocks. Complete letters or numerals of 'anydesired form or configuration may be marked upon the sides, Zlib, of theblocks, either by first printing them upon paper or other suitablematerial, and then pasting them to the said sides, or by painting them'directly upon the same, o1 by any" other suitable means. Upon each ofthe triangular sides or ends, a, is marked a portion of a letter ornumeral, in such a way that whenthe rectangular quadrilateral sides oftwo certain blocks are placed `together,they'form a cube, the letter ornumeral, as the casemay be, will be formed complete. upon the contiguousends. of the two blocks,.as clearly shown in igs. 1 and 3. By thisconstruction of the` blocks, and the within-described disposition of theletters upon them, great opportunity is alorded for the exercisefof themental faculties, not only in the arrangementof the blocks themselves,asin making toy-buildings and` similar objects, but in the selection`and joining of those blocks, the ends or sides, 11, of which aremarked'with portions of the same letter or numeral, as hereinbefore setforth. v

What I claim as new, and desire to secure by Letters Patent, isf- A vThe building-blocks, of the form of the half of a cube, havinglive'sides, in combination with letters or numerals on their surfaceswhich are whole in themselves,

described, for the purposes specied. GEORGE H.` GHINNOCK.
